Rio Challvayacu Fishing in Región de San Martín

Flat light and a covered sky today, with the water lying quiet with pressure dropping. The fish at Rio Challvayacu are likely to sit near the seam between weed and open water. The morning should out-fish the rest of the day. Small adjustments will matter more than big moves. Spring water is still waking up, so the shallows warm first.
